ABOUT YOUR KIT


Congratulations on your purchase of the HYDRO X SERIES iCUE LINK XH505i RX 360 RGB Custom Cooling Kit.

As you embark on your custom cooling journey, it's essential to understand the best practices that will ensure optimal performance and longevity for your system. This introduction aims to provide you with a foundational understanding of custom cooling and how to make the most of your new kit.

The XH505i RX 360 RGB is more than just a collection of parts; it's a comprehensive solution designed to take the hassle out of building. With the integrated iCUE LINK technology, installation becomes a breeze, reducing cable clutter and ensuring a streamlined setup. The vibrant RGB LEDs, combined with top-tier components like the XC7 RGB ELITE CPU Water Block and XD6 RGB ELITE Pump/Reservoir, promise both aesthetics and performance. And with the added convenience of the hardline bending/cutting kit, you have everything you need to achieve the breathtaking visuals that only hardline loops can deliver.

Remember, while this kit provides a solid foundation, the beauty of custom cooling lies in its flexibility. While a GPU block isn't part of this kit, extra fittings are provided should you wish to expand your loop to include one. Each component in this kit comes with its own Quick Start Guide to assist you with the installation process. Simply follow the links provided in the HOW-TOS & QUICK START GUIDES section to access the individual guides.

Thank you for choosing the XH505i RX 360 RGB Custom Cooling Kit.

CUSTOM COOLING BEST PRACTICES


PLAN YOUR BUILD

Before starting, lay out all components and visualize the loop. This will help you identify the best path for tubing and ensure efficient flow.


CLEAN THE RADIATOR

Before installation, please make sure to clean the radiator.

WARNING: Do not use strong acids, bases, or alcohol-based solutions to clean the radiator. CORSAIR does not recommend the use of third-party radiator cleaning agents - doing so may void your warranty.

Please follow these guidelines for proper cleaning:

  • Internals: Flush the radiator using distilled water only. If especially dirty, add a small amount of dishwashing soap to help remove the grease or residue. A thorough rinse with distilled water is required.
  • Externals: Use compressed air and a soft brush to clean the outside. Keep at least 10 cm (4") between the nozzle and the radiator surface.

PERFORM A LEAK TEST

After setting up your loop, always perform a leak test for at least 24 hours. This ensures that all connections are secure, and your components safe. CORSAIR warranty does not cover any hardware damage resulting from poorly executed, improper, or otherwise hasty assembly of your custom water-cooling system.


BLEED THE SYSTEM

After filling the loop, run the pump to circulate the coolant and release any trapped air bubbles. More details about this process are described in the XD6 ELITE quick start guide.


OPTIMIZE THE FLOW RATE

Ensure that your pump's flow rate is suitable for your loop size. A flow rate that's too high or too low can affect cooling efficiency. There is no need to run pump at 100%, as the added value of extra flow is minimal while it is reducing the pump longevity. Running your pump at 40–70% PWM typically provides a good balance between performance, noise, and pump longevity.


MAINTENANCE


Custom cooling loops require regular maintenance. It's recommended to check the coolant level and inspect for any blockages or algae growth every few months. A full system flush should be done annually for optimal performance.
